About the Airtac BC Series Air Treatment Combination (Filter Regulator Lubricator) BC3000A4
The BC3000A4 is AirTAC's B-line three-unit air preparation set in the 3000 size, assembled from the BF3000C filter, BR3000C regulator and BL3000C lubricator on PT3/8 ports. The A in the order code engages the B-line automatic drain, so condensate leaves the 40 cc bowl without an operator opening it, while the lubricator reservoir carries 60 cc of ISO VG32 turbine oil.
The final digit 4 selects the GS40 gauge scaled in kgf/cm2 and psi, handy where legacy dual-scale readouts are mounted on the panel. Regulation spans the standard 0.15 to 0.9 MPa (20 to 130 psi), with 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure. The standard 40 um element handles the general grit load, and the set operates from -5 to +70 C with no freezing.

How to choose
Within the BC3000 family, this code differs from BC3000AL1 and BC3000L1, which cap output at 0.4 MPa for low-pressure circuits; the BC3000A4 keeps the full 0.9 MPa standard range. The base BC3000 code (blank drain) uses differential plus manual discharge instead of the automatic drain chosen here, BC2000 (PT1/4) steps down in port size and BC4000 (PT1/2) steps up. If your plant runs G or NPT threads, order the codes ending in G or T rather than this PT version.
Applications
Compressor drop for a machining cell
On a PT3/8 takeoff from a plant ring main, the automatic drain keeps the 40 cc bowl clear between maintenance rounds, and the 40 um element screens general line grit before regulators and tools.
Packaging machinery air supply
Wrapper and cartoner valves benefit from the BL3000C lubricator's 60 cc of ISO VG32 oil mist, while the BR3000C holds setpoints across the 0.15 to 0.9 MPa span read in kgf/cm2 and psi.
Conditioning ahead of directional valves
Feeding cylinders and valves on a 3/8 header, the set delivers filtered, regulated and lubricated air; the kgf/cm2 and psi dial lets mixed-standards crews set the same pressure without conversion.
FAQ
Which figures define the BC3000A4?
PT3/8 ports; BF3000C filter, BR3000C regulator and BL3000C lubricator; 40 cc drain bowl with automatic drain; 60 cc lubricator; 40 um element; GS40 gauge in kgf/cm2 and psi; regulating range 0.15 to 0.9 MPa (20 to 130 psi); maximum pressure 1.0 MPa (145 psi), proof pressure 1.5 MPa (215 psi); operating temperature -5 to +70 C.
How does the A option change day-to-day maintenance?
On the B-line, A selects automatic drain instead of the differential-plus-manual drain of the base BC3000, so the 40 cc bowl ejects condensate on its own and staff only need to check that the mechanism works periodically; confirm the service details from the AC/BC datasheet.
